Switch



FIG. 1 is a perspective view of the switch showing my new design;

FIG. 2 is a front view of FIG. 1;

FIG. 3 is a rear view of FIG. 1;

FIG. 4 is a left view of FIG. 1, the right side view being substantially a mirror image therefore; and,

FIG. 5 is a top plan view of FIG. 1.

The bottom of the switch forms no part of the claimed design. 

I claim an ornamental design for a switch, as shown and described.
